Tank car aluminum plate use some aluminum alloy

Market commonly used tank car aluminum plate length of 12.5 meters, width is less than 2.2 meters, the thickness is usually 5, 6, 7, 8 mm, a full tank car tanks, general need 4 to 6 pieces of aluminum plate welding and become, one of the most important body adopts 5083 h111 aluminum plate, on both sides of the pot cover is 5083 – O aluminum plate, O state more softer, which can cover need to bend, clapboard part adopts is 5083 – O state. In addition, some manufacturers use 5454H111 aluminum plate to produce tanks.
Aluminum plates for tank cars are mainly 5 series and 6 series related products. The 5 series are aluminum alloys with magnesium as the main alloy element, and the 6 series are aluminum alloys with magnesium and silicon as the main alloy elements and Mg 2Si phase as the strengthening phase. The main alloy brands include: 5052 aluminum plate, 5083 aluminum plate, 5754 aluminum plate, 6061 aluminum plate and 6082 aluminum plate.

The 5052 aluminum plate is al-mg alloy aluminum plate, which is the most widely used type of anti-rust aluminum with high strength and corrosion resistance. However, it can not be strengthened by heat treatment, and the plasticity is still good in the case of semi-cold hardening, and low in the case of cold hardening, which can be polished.
The magnesium alloy in 5083 aluminum plate has high strength, heat treated alloy, good machinability, corrosion resistance and welding performance. It is widely used in traffic vehicles, such as ships, planes, vehicles and pressure vessels (liquid tanks, refrigerated vehicles, refrigerated containers).
The 5754 aluminum plate is a typical alloy of al-mg alloy due to its medium strength, good corrosion resistance, weldability and easy processing. In foreign countries, 5754 aluminum alloy plates with different heat treatment conditions are the main materials used in automobile manufacturing (car door, mold, seal) and canning industry.
The 6061 aluminum plate has medium strength, good corrosion resistance, weldability, good machining and anodizing coloring. Because it contains a small number of Cu, its strength is higher than 6063, and its quenching sensitivity is higher than 6063. After extrusion, air quenching cannot be achieved, and it can only be achieved after re-solid solution treatment and quenching aging.
The 6082 aluminum plate is an aluminum sheet which can be strengthened by heat treatment. It has medium strength, good welding performance and corrosion resistance. It is mainly used in transportation and structural engineering industry.
